A synchronize operation should be performed on a dictionary under the following circumstances:
A field’s data type reference is stored with the window, table, key, report and global variable resources for faster processing. If the data type changes, synchronizing the dictionary will ensure all references to the data type are correct. The synchronize utility also recalculates the buffer sizes for tables and windows.
To synchronize a dictionary, simply choose Synchronize from the Utilities menu. A progress dialog will be displayed as the dictionary is synchronized.
For large dictionaries, the synchronize operation may take several minutes.
